We went to bed, at last, and went quickly to sleep, but I woke up, after about three hours, with throbbing temples, and a head which was physically sore, outside and in. I was dazed, dreamy, wretched, seedy, unrefreshed. I recognized the occasion of all this: it was that torrent. In the mountain villages of Switzerland, and along the roads, one has always the roar of the torrent in his ears. He imagines it is music, and he thinks poetic things about it; he lies in his comfortable bed and is lulled to sleep by it. But by and by he begins to notice that his head is very sore--he cannot account for it; in solitudes where the profoundest silence reigns, he notices a sullen, distant, continuous roar in his ears, which is like what he would experience if he had sea-shells pressed against them--he cannot account for it; he is drowsy and absent-minded; there is no tenacity to his mind, he cannot keep hold of a thought and follow it out; if he sits down to write, his vocabulary is empty, no suitable words will come, he forgets what he started to do, and remains there, pen in hand, head tilted up, eyes closed, listening painfully to the muffled roar of a distant train in his ears; in his soundest sleep the strain continues, he goes on listening, always listening intently, anxiously, and wakes at last, harassed, irritable, unrefreshed. He cannot manage to account for these things. Day after day he feels as if he had spent his nights in a sleeping-car. It actually takes him weeks to find out that it is those persecuting torrents that have been making all the mischief. It is time for him to get out of Switzerland, then, for as soon as he has discovered the cause, the misery is magnified several fold. The roar of the torrent is maddening, then, for his imagination is assisting; the physical pain it inflicts is exquisite. When he finds he is approaching one of those streams, his dread is so lively that he is disposed to fly the track and avoid the implacable foe.
